' SALES BOOK.

' Application vled April 29,

To all whom t may concern:

'Be it known that l, JAMES H. Prr'rs, a citizen of the United States, and resident of McKeesport, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful lmprovements in Sales Books, of which the following is a specication.

This invention relates to manifold sales books, and more particularly to books of this class for making triplicate sales records, and has for one of its objects the provision of a novel carbon sheet for such books.

Another object of the invention is the..pro` vision of a novel bookl of this class in which one of the records will be made on both sides of a transparent sheet, thus providinga distinct record.

A still further object of the invention is to provide a record on the transparent sheet that will effectively prevent'alterations after it kgs been made.

T e above and other olojects and advantages will be more fully brought out in the following specification and illustrated in `the accompanying drawings, in which- Figure 1 is a perspective view 'of a manifold sales book showing one embodiment of this invention. y l l Figure 2 is a plan view of the carbon sheet employed in carrying out'this invention.

Figure 3 is a diagrammatic' line'drawing illustrating the position of the several record sheets and carbon sheet when inoperative position.

Referring more particularlyto the'draw# ings, the numeralffZ designatesthe bottom-l cover of a sales book' holder to which the `top cover 3 is connected along one olf' its longitudinal edges by a dexiblehinge d. 'At' the opposite longitudinal'edge of the loot-I tom cover 2 .is a'lsecondexible hinge 5 for connecting an auxiliary vhacker.support 6 therewith; 'lhe back orsuppert 6 carries a record pad 7 for receiving the inscription, the pad comprising fay plurality of sets 'of double leaves .'eomposed ot,- original vand duplicate record sheets`8vand 9,' respectively,

' divided by a line of perorations 10.v The pad 'l' `is secured to support G by .a spring psessed clamping member 11 havingteeth 12 adapted to engagethe pad.

A triplicate pad composed of aback 13 and translucent or 'tissue' leavesor inter'- 1922. Serial No. 557,369.

vcarbon sheet is provided with a carbon for its entire length,'while the lower face is f1 provided witha carbon face for only one-- halt its length, thus leaving the lower .halt of its length bare, as at 18.

ln practice the folded carbon-member folded upon itself so that the full length oi: carbon is inside and forms opposite carbon faces, and the half length or carbon is on the bottom, and the' carbon is interposed in this position between the original and duplicate record sheets 8 and When it is desired to use' the book, the original record Sheet 8 and top half of carbon (the length of single carbon 17) is pulled upwardly away from the duplicate sheet 9 and lower half of carbon, and one of the tissue sheets or leaves lll of the triplicate pad is interposed between the halves of the carbon sheet, and the top half of the ,carbon sheet and original record sheet are replaced over the tissuesheet. When thus positioned any insoription on the original record sheet 8 will be duplicated on both sides of the triplicate tissue'sheet 14 and on the top side of the -'duplicate sheet 9. Thus a clear and distinct copy is made on the tissue sheet 14, a good duplicate copy is made, and the back of the original sheet 8-'is kept clean and free of carbon.

Another feature of the double copy on the tissue is that such a copy is almost impos-I or pads, and `many modifications of its application will readily Suggest themselves to those skilled in the. art.

ll daim-- In a manifold sales book, a back, superposed sets of original and duplicate leaves secured to the back, a plurality of single tiss'ue intersheets secured to the back adjacent one edge of the sets of leaves. and to be intei'posed singly between the original and duplieate leaf and the underside of an interposed intersheet, I respectively, said doublel face transfersheet having a longitudinal extension' of that transfer face only which' is to be in Cooperative relation with the-underside of the said interposed intersheet, whereby,v

said extension lmay be folded back to lie between the original sheet and the intersheet with its transfer face in cooperative relation `l witlithe upper face of the'intel-'sheet ln... testinony whereof I have hereunto signed 'my namef,I
